Abstract

The invention discloses a power generation system taking magnesium as fuel and a working method thereof. The power generation system comprises a magnesium fuel electrolysis preparation subsystem, a magnesium combustion and combustion product collection subsystem and a steam Rankine cycle power generation subsystem. By effectively coupling magnesium fuel energy storage, magnesium combustion power generation, steam Rankine cycle, magnesium oxide electrolysis regeneration and the like, the power generation system has the advantages of high energy storage density, long energy storage period, permanent storage, no consumption in fuel circulation regeneration, convenience in development of global energy trade and the like.

Description

technical field [0001] The invention belongs to the technical field of green cycle power generation and advanced energy storage, and specifically relates to a power generation system using magnesium as fuel and a working method thereof. Background technique [0002] With the increasingly serious situation of global air pollution and climate warming, the traditional power generation system based on fossil energy will face unprecedented pressure and challenges. From a global perspective, countries are trying to increase the proportion of renewable energy in their power structure. In the future, the development trend of the world's energy field will inevitably be that renewable energy will gradually replace fossil energy. However, due to its intermittent, unstable and uncertain characteristics, renewable energy seriously hinders the development of renewable energy power generation. In order to replace fossil energy with renewable energy in the future, we must rely on the deve...
